Delphi Conversion Unicode Issues

Question

We have large commercial app that we want to convert from Delphi 6 to 2010. Approx 10 3rd party component sets, all with source code... I have heard warnings about Unicode

Answer 1

Another point to take care of, is the usage of Variant types with strings and the VarType function testing for strings: one needs to use varUString instead of varString.

Assuming AValue is of type Variant and has being assigned a Unicode string value, the following won't work:

  if VarType(AValue) = varString then ...

and needs to be changed to

  if VarType(AValue) = varUString then ...
